TILE ROOF AND ROOFING-TILE.

Patented J an. 5, 1915.

Application filed. March 15, 1912, Serial Ito. 683,962. Renewed August22, 1914.. Serial No. 858,127.

To all whom it may concern:

Be it known that I, WILLIAM A. BRUNCK- HORST, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented new and useful Improvements in Tile Roofs andRoofing-Tiles, of which the following is a. specification.

The object of my invention is to furnish a tile roof of exceptionalstrength, considering its weight; to facilitate manufacture and layingof the tile; and to secure closeness of joints, so as'to preventleakage.

In the drawings Figure 1. is a plan view of a roof formed of tilesembodying my improvements; Fig. 2. is a section on line 9-2 in Fig. 1;Fig. 3. is a section on line 3-3 in Fig. 1; Fig. I. is a section on line4.4 in Fig. 1; and Fig. 5. is a plan view of the under side of a maintile embodying my improvements.

Referring to the drawings, my roof is constructed mainly of tiles 6,consisting of a flat bodv ordinarily about twice as long as wide, whichon its upper side is provided with ribs 7 adjacent to its longer edges,and which on its lower side, along its whole circumference, is providedwith a heavy rib 8, a lip 9 projecting downward beyond rib 8 along oneof the ends of tile 6; these features being modified however by thetermination of ribs 7 a short distance from the ends oftile 6, and bythe provision of a semicircular groove 10 in rib 8 at the middle of theend of tile 6 opposite the end at which lip 9 is located. In conjunctionwith tiles 6 I employ caps 11 which are of a length equal to that oftiles 6, are of semitubular section, save that their ends 12 are madesolid for a length equal to the distance to which ribs 7 approach theends of tiles 6, and which are of dimensions such as to be able toaccommodate below them two ribs 7 of adjacent tiles 6 and to snugly fitinto groove 10 of any tile 6. v

In laying my roof I use preferably a substructure of steel withhorizontal purlins 13. On the lowest pair of these purlins I place a rowof tiles 6 side by side with lips 9 hooked over the upper purlin, andthe other ends, containing grooves 10, resting on the purlin below. Ithen place caps 11 over each pair of adjoining ribs 7, and thereuponplace another row of tiles 6 with their lips 9 hooked over the nextpurlin above and their lower ends resting on the lower row of tiles 6and caps 11, disposing of tiles 6 in the upper row so that their grooves10 will fit over caps 11 in the lower row, thus breaking joints;thereupon I place caps 11 over ribs 7 in the upper row; and thuscontinue until my roof is completed.

While my tiles and caps are intended to be constructed chiefly ofreinforced concrete ribs 8 being particularly useful for the placing ofreinforcements,-I do not wish to confine myself to that material.

It is evident that instead of using ribs 7 and caps 11, I may adoptother means of closing the vertical joints between tiles 6, such aspitch etc., omitting in such case grooves 10.

I claim 1. In tile roofs, the combination of suitable means of support,with main tiles (ibeing fiat on their upper surfaces, save as to tworibs 7 projecting along two opposite edges, and having on their lowersides a rib 8 along their whole circumference, with a lip 9 dependingbelow such rib along one of the edges of such tile not provided withribs 7, and a groove 10 formed in said rib 8 at the middle of the edgeof each tile opposite the one provided with lip 9; and semi-tubularauxiliary caps 11 fitting over adjoining ribs 7 and into grooves 10, andhaving solid ends 12.

2. As a new article of manufacture, a roofing tile 6 being fiat on itsupper surface save as to two ribs 7 projecting along two opposite edges,and having on its lower side a rib 8 along its whole circumference, witha lip 9 depending below such rib along one of the edges not providedwith ribs 7, and a groove 10 formed in said rib 8 at the middle of theedge opposite the one provided with lip 9.
